|Requirement is that you have to have the flash plugin install on your system. Go here to test the plugin. http://www.adobe.com/software/flash...|
Animation should play near the top of the page and tells you the version build of the plugin you have installed. If it detect that you don't have flash installed on your system, it will let you know.
If it doesn't detect flash installed on your system go here to download adobe flash for your system. http://get.adobe.com/flashplayer/
Might be a good idea to update flash if you do have a older version. Could be that youtube and facebook have issues with older version.
